Didj and Explorer MMC Patch
The original source code for the MMC drivers that were released for the LX were not completed but lucky for us there was a patch included that finishes them to a usable state.
Notice: Hot swapping is not supported yet and may lead to data loss in the event that the card is not unmounted before it is removed.
As these drivers haven't been through extensive testing you should backup any important information on the card before use.
to apply these patches just copy them to /drivers/mmc/host/ and type the following
patch lf1000_mmc.c < mmc_patch_lf1000-sdio.patch patch Kconfig < mmc_patch_Kconfig.patch
now when you do a make menuconfig build the MMC drivers as modules by typing the following:
make -j Number of cpu cores+1 sudo make modules_install
and your modules will be in /lib/modules/2.6.31-leapfrog on your system ready for you to copy them over
it is best to copy them to /lib/modules/2.6.31-leapfrog/kernel/drivers/mmc/
and then run:
on your device.
Reboot the device with the kernel you just compiled (it is now enabled for the mmc device modules).
Using the kernel you just built, when you want to mount a card simply type the following to load the modules
you will then see something like this:
XXX: checking for SDIO... XXX: checking for SD... XXX: SD... mmc0: host does not support reading read-only switch. assuming write-enable. mmc0: new high speed SDHC card at address 0007
you will then see something like the following
mmcblk0: mmc0:0002 00000 3.82 GiB mmcblk0: p1
type the following to add the device such that it can be mounted (only need to do this once, the first time)
To mount the card type
mount /dev/mmcblk0p1 /mnt
and you will then have access to the files on your micro sd card in the /mnt directory
to unmount the card simply type
much thanks to zucchini for the help
